I'll give 100 pts and brainliest if you answer this!!! thank you for the help boo

Perform the operation. Write the answer in standard form.
1. (6 − i) + (9 + 5i)
2. (7 + 3i) + (11 + 2i)
3. (12 + 4i) − (2 − 15i)
4. (3 − 7i) − (3 + 5i)
5. 7 − (2 − 3i) + 6i
6. −16 + (3 + 4i) − 4i
7. 3i(6 − 5i)
8. −2i(8 + 2i)
9. (−5 + i)(8 − 6i)
10. (3 − 6i)(−1 + 7i)
11. (2 + 5i)(2 − 5i)
12. (−3 − i)(−3 + I)
13. (4 + i) 2
14. (5 − 9i) 2

Step-by-step explanation:

Standard form means to put the terms in order based on their exponent (x³ -> x² -> x -> constant)

1. (6 - i) + (9 + 5i)

2. (7 + 3i) + (11 + 2i)

3. (12 + 4i) - (2 - 15i)

4. (3 - 7i) - (3 + 5i)

5. 7 - (2 - 3i) + 6i

6. -16 + (3 + 4i) - 4i

7. 3i(6-5i)

8. -2i(8+2i)

9. (-5 + i)(8 - 6i)

10. (3 - 6i)(-1 + 7i)

11. (2 + 5i)(2 - 5i)

12. (-3 - i)(-3 + i)

13. (4 + i) * 2

14. (5 - 9i) * 2

:p when I first started answering this I thought the parentheses were being multiplied every time and did 100x more work .-.

Hope it helps <3 :D

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
